FGZ100 series comprehensive microcomputer protection device
Product Introduction
The FGZ100 series comprehensive microcomputer protection device is mainly used in power plants and substations with voltage levels below 35KV, to achieve functions such as protection, measurement, and control of their high-voltage switchgear.
This series of products features a large screen Chinese LCD display, fully enclosed shockproof aluminum alloy chassis, back plug-in structure, independent protection and signal outlets, and standardized hardware modules. It highlights the solution to the long-term reliable operation and conventional control of microcomputer protection devices in harsh environments such as high cold, multiple lightning strikes, low temperature, humidity, strong electromagnetic interference, harmful gases and dust. It can be used for the renovation of old power plants and substations, as well as for the construction of new power plants and substations to directly form a microcomputer comprehensive automation system.
The device mainly adopts computer technology, high-speed data processing technology, power electronics technology, etc., integrating multiple functions such as protection, measurement, control, monitoring, and display. It can replace traditional secondary circuits and achieve intelligent control of switches. It can be applied to various types of switchgear and wiring systems, such as single busbar, double busbar, bypass busbar, and dual power supply systems. It can be installed separately on the switchgear or centrally assembled into screens. It can also be connected to the backend system through bus communication to form a power automation system.
